I would like to give all of my praises and gratitudes to Allah SWT for the blessing, mercy, and favor so that I could finish this Final Project which titled Unbalanced Three Phase Power Flow Study for Java-Bali 500 kV Interconnection System under Balanced Load Condition. This Final Project Report is one of the requirements for the completion of my study in Electrical Engineering Department, Institute of Technology Bandung.
